- 摘要:
- 以“韩国甜椒”为试材,研究外植体种类、苗龄、基本培养基种类、激素组合等多种因素对辣椒组织再生的影响。结果表明:带柄子叶再生能力较子叶和下胚轴切段强,14 d苗龄幼苗的外植体芽分化率较高,最佳芽分化培养基为MB+4.5 mg/L BA+0.5 mg/L IAA+4 mg/L AgNO3+200 mg/L Cef,最佳芽伸长培养基为MS+3 mg/L BA+0.3 mg/L IAA+2 mg/L GA3+4 mg/L AgNO3+200 mg/L Cef,生根培养基先用1/2MS+0.4 mg/L NAA+4 mg/L AgNO3,继代用1/2MS+0.4 mg/L NAA+0.2% 活性炭。
- Abstract:
- The effect of different explants,age of seedling,different basic mediums and combinations of hormones on plant regeneration were investigated by using the variety of pepper(Capsicum annuum L.)‘South Korea pepper’ as experiment material.The results showed that cotyledon with petiole taken from 14-day-old seedlings was much easier to induce regeneration than cotyledon and hypocotyl.The optimal medium for the differentiation of pepper buds was MB+4.5 mg/L 6-BA+0.5 mg/L IAA+4 mg/L AgNO3+200 mg/L Cef,the medium for the bud elongation was MS+3 mg/L 6-BA+0.3 mg/L IAA+2 mg/L GA3+4 mg/L AgNO3+200 mg/L Cef and the medium for rooting culture was 1/2MS+0.4 mg/L NAA+4 mg/L AgNO3 and 1/2MS+0.4 mg/L NAA+0.2% activated carbon as subculture medium.
